<u>in winter</u>. As you mentioned, tie-down the leader in early spring, but don’t forget to bring it back up after bud break and before it stiffens in mid-summer (early July in Illinois). You can also make a notch
<u>above</u> dormant buds on the leader to break the apical dominance effect. Or you can brush/spray the blind-wood areas of the leader with Promalin. Promalin is a growth regulator, so its effect is subject to many factors including temperature, rootstock,
tree vigor, spur/non spur, etc. <u></u><u></u></span></p>

<p class="MsoNormal">I am next to a commercial tree nursery. They Shepard hook tie down in Spring to promote lateral growth. A few youtube videos about tall spindle indicate to do head in mid summer if the trees are tall enough. No one has ever talked about
shepard hooking tall spindle. The literature I can find online is silent on heading or shepard hooks.<br clear="all">
